3 Claims.

The invention has relation to means for fastening the ends of the shoulder straps or tapes for womens undergarments onto the slide buckles commonly used therewith, this fastening being 5 usually by sewing, which a slow process.

An object of the invention is to provide improved fastening means for this purpose which will serve the purpose as well or better and save considerable time, thereby materially increasing production and decreasing cost of operation. Another object is to provi-e an attachment for the stapling machine used, adapted to facilitate rapid work and accomplish better work.

F The invention consists in the novel construction and combinations of parts as .set forth in the appended claims.

In the accompanying drawing illustrating the invention,

Figure 1 is a front view of the attachment as applied to a stapling machine, showing the strap in full lines and the slide buckle in dotted lines.

Figure 2 is a section on the line 22, Figure 1, through the attachment, slide buckle and strap, the machine being in full lines.

Figure 3 is a plan view of the attachment, the machine being broken away.

Figure 4 is a perspective view of the attachment.

Figure 5 is a similar view of a modification.

Figure 6 is an edge view of the strap and slide buckle.

Figure 7 is a perspective View of a slide buckle and a portion of a strap stapled thereto.

Figure 8 is a bottom plan view of the same.

In this drawing, the numeral 1, designates the shoulder strap or tape, and 2, is the slide buckle, one end of said strap being engaged with the center bar of said buckle and the reversely turned end lapped with and secured to the body of the strap to hold the buckle and strap together, the securing means previously used being sewing as stated.

In the present case, the staple 3 is used in place of the sewing, the staple being of very fine wire, and the body of the staple and the clinched ends 4 or" the staple prongs being obliquely disposed relatively to each other, said clinched ends being laterally spaced from and lapping each other,

, whereby the securing effect is increased and the O staple is enabled to be engaged effectually with the narrow strap.

As the slide buckles are quite small, and the shoulder straps or tapes are also diminutive, and the fingers of the hands of the operator are comparatively large, difficulty is experienced in accomplishing the stapling with any degree of speed.

Applicant has therefore devised means for speeding up the work and accomplishing better work, this being a stapling machine attachment comprising an elongated horizontally extending vertically disposed guide bar 6 leading to the anvil and plunger of the machine, and having at its inner end a U-bend '7 and a reversely extending attachment portion 8, secured to the base of the machine. The guide bar is provided with a vertical face 9, which is adapted to be engaged by the slide buckle, and a longitudinal slot 10, wherethrough passes horizontally the end of the shoulder strap laced onto the slide buckle, tension exerted by the operator upon the shoulder strap end causing the slide buckle to assume an upright or vertical position against vertical face 9 of the guide bar.

The slide buckle and the shoulder strap with one end thereof laced onto the buckle is fed by the operator to the guide bar, the strap being entered into the open end 11 of the slot 10, and tension being exerted upon the strap, the buckle is held upright as stated, out of the way of the stapling plunger and anvil, and properly spaced therefrom, and when the buckle and the laced strap end arrive in line with the anvil and plunger, the closed end 12 of the slot 10 forms a stop for the feeding movement, the plunger being then depressed by the operator to accomplish the stap ling, this being usually done by means of a treadle.

The shoulder strap and the attached slide buckle are then reversely moved until the strap passes out of the open end of the slot, after which the operation is repeated with another slide buckle and shoulder strap.

A modification of the guide bar is shown in Figure 5 of the drawing, wherein the guide bar slot is provided at one end with an enlargement 13, which is approximately of the size of the slide buckle and is located in the bend of the guide bar, this slot enlargement being at the end of the guide bar opposite the open end 11 therei of. With this modification, the feeding movement of the strap and slide buckle may be continued unidirectionally after the stapling is effected whereby the shoulder strap and the attached slide buckle will pass out of the slot enlargement 13, and a reversal of the feeding movement will not be needed.

I claim:--

1. A stapling machine attachment, comprising an elongated horizontally extending vertically disposed guide bar leading to the anvil and plunger of the machine and having at one end thereof a U-bend and a reversely extending attachment portion, said guide bar having a vertical face for engagement with a slide buckle to hold it upright out of the way of the said anvil and plunger and properly spaced therefrom, and a longitudinal slot one end of which is open for entry of a shoulder strap.

2. A stapling machine attachment, comprising an elongated horizontally extending vertically disposed guide bar leading to the anvil and plunger of the machine and having at one end thereof a U-bend and a reversely extending attachment portion, said guide bar having a vertical face for engagement with a slide buckle to hold it upright out of the way of said anvil and plunger and properly spaced therefrom, and a longitudinal slot one end of which is open for entry of a shouder strap and the other end of which is closed and forms a stop for the feeding movement when the lapped reversely turned end portion and body of the strap arrive in line with the anvil and plunger of the machine.

3. A stapling machine attachment, comprising an elongated horizontally extending vertically disposed guide bar leading to the anvil and plunger of the machine and having at one end thereof a U-bend and a reversely extending attachment portion, said guide bar having a vertical face for engagement with a slide buckle to hold it upright out of the way of the said anvil and plunger and properly spaced therefrom, and a longitudinal slot one end of which is open for entry of a shoulder strap and the other end of which is provided with an enlargement located in the U-bend of the guide bar to permit escape of the slide buckle in a unidirectional feed of the slide buckle and strap end laced thereof to the anvil and plunger and outwardly away therefrom.
